Used GMC cars for sale near Montclair, CA under $40,000

Overall loved how welcoming they were and how they gave me recommendations of what I need to get done. The fix my issue in about a hour.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Luis Aguirre and Jose Vargas helped me out and made everything very easy. I would recommend coming in and working with them !

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I bought a Chevy Silverado from LSM Cars and had a great experience overall. The staff was friendly and very knowledgeable about the inventory. Erika and Mike made sure everything was handled properly and efficiently. The pricing was fair and the process was transparent. This dealership truly cares about their customers. I’ll definitely be back in the future.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

Michael Jacobs made the car buying process seamless when I purchased my 2025 Yukon AT4 diesel. He was extremely helpful and polite😊 Rod Shelffo in Finance was awesome to work with as well!

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

I been coming to this guys for couple years now. They never let me down. We as a family collectively bought 3 cars here and each time they helped us out. My sales and finance reps where Marlene and Teo. Super happy.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

I have bought 2 work trucks from this place and they were both good and reliable. The sales people were pretty good except for the second time around, he actually got frustrated when my wife started reading the contract before signing. The only issue I have is both times I purchased, the trucks gas tanks were on empty and they wouldn't put any gas in them for me. The second truck I bought, the tank was so empty that I was stressed leaving the place just hoping to make it to the gas station across the street.

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

Leo at Pro X motors was amazing. I got a very good deal on a decent 2016 X3. Leo was a pleasure to work with, worked hard to get the deal done and I left with the car I wanted for a very good price. I would recommend Pro X Motors to anyone looking for a competitively pre-owned vehicle. Thank you very much!!

This Yukon is very roomy, comfortable, has tv for my kids. New tires, great condition Best vehicle I have ever owned. I highly recommend it.

I was running late past there closing time. They were very gracious and waited for us. Very nice to do business with.

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Roy went above and beyond in making sure I am happy with my deal. He called me days later to follow up. That is the kind of after-sales service you would like. The dealership is also clean and very accessible. I would highly recommend this dealership to all my friends and family.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Very happy with our car purchase for our daughter. we found the perfect civic for our daughter on cars.com. The whole process was easy . There was no haggling price at the dealer. We were in and out of office quickly. Thank u guys.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Had a great and smooth experience buying a car with Anthony and Jose. Would highly recommend getting a car here!!

I love it so much lots of space .. every thing clean no dents or scratches every thing is perfect all everything fully loaded the best

Just purchased a Chevy Tahoe, with Jose and there team, and went excellent and smooth. Highly recommend this place! Thank you pro x motors.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

After getting the run around from multiple dealerships in LA/OC/IE I visited Auto Republic. Yes, I had my guard up after all the financing and heavy down payments other dealerships we're asking for before even giving me attention. The showroom was clean and the lot had so many dream cars. I found the perfect car for my family and had the assistance from the manager that was top notch. I'm writing this review since the single star reviews show the lack of reading details about add on features. Don't get upset with a dealership for having tracking on a car (saves on insurance) along with other key options that are great for your next car. I've referred family and friends, all had exceptional purchasing experiences and I'll get my next vehicle here as well.

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

I knew I was gonna like it here when the salesman Angel approached me with the most welcoming greeting. I came with a car and budget in mind and the whole team there helped me. 10/10 would recommend

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

I bought my Suburban just about 2 months ago from Diamond. From the moment I called, Claudia and Neil were very friendly and helpful. I live about 50 miles from their location so they made everything as easy as possible. In the end I ended up buying the car from them and it was one of the easiest and best car buying experiences I've had, they were willing to work with me on payments and pricing and threw in a warranty on top of all that. I was very please with them and I would definately refer them to anyone who is looking for a good used car. They are no hassel, easy to work with and not looking to get over on anyone! If your worried about buying from a smaller dealer you don't need to worry with them!

Strong body and smooth and safe ride, but still has such a comfortable soft feel . Wonderful for road trips and towing. Sleek design. Excited to take on trips around US.

The experience here at Car Castle was by far the Best car buying experience my wife and i have ever had. Thank you Eddie the (Manager) for helping and assisting us with the whole buying process and for giving us a Great Deal!

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Thank you Yocelin for making this fast . First time buying a car didn’t know what to expect but metro auto made it super easy

This is a really nice vehicle for being used. It exceeds our expectations for comfort and performance. We enjoy driving it both in town and out in the country.

Kris was great! Had a lot of patience with me and definitely will recommend him for your next car purchase.

I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Jerry from the start helped me every step of the way, did everything he could. Very friendly, whole staff made us feel welcomed. I am still thankful they were able to make it all happen. Definitely recommend going to WCA!!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain
